The Qlogic architecture is a bit more > automatic transmission-like.... The approach you mention is what the FC standards advocate, I think it is a good thing to layer it. Some other things that need thought, esp. on fabrics: how to 'wire down' a FC device. I think something like: disk da0 at fcloop 0 wwn=<64bitnumber> disk da1 at fabric 1 wwn=<64bitnumber> Maybe one could even omit the fcloop 0 stuff, as the wwn should be sufficient, being worldwide unique etc. These are currently some first random thoughts.. > > Well, fabrics are a bit on the expensive side.
